Distributions of EBV DNA load, infection status, and mortality. (A) EBV DNA levels in different age groups. 1–5 years group vs. 5–12 years group, P < 0.001; 1–5 years group vs. 12–18 years group, P < 0.001. (B) EBV DNA levels in different disease types. IM vs. HLH, P < 0.001; IM vs. pneumonia, P < 0.001; IM vs. others diagnosis, P < 0.001; sepsis vs. pneumonia, P < 0.001; sepsis vs. others diagnosis, P < 0.001; HLH vs. pneumonia, P < 0.001; HLH vs. others diagnosis, P < 0.001; pneumonia vs. CAEBV, P < 0.001; pneumonia vs. others diagnosis, P < 0.001; and CAEBV vs. others diagnosis, P < 0.001. (C) The proportion of primary infections and Activation-IgG⁺ across different disease types. (D) Mortality rates across different EBV DNA levels and infection states. (E) Violin plot of ALT levels at different levels of EBV DNA. (F) Violin plot of AST levels at different levels of EBV DNA
